# WhoLayer vs ZoomInfo

ZoomInfo in one line: Large B2B data platform for sales and marketing, now also selling a self-serve, agent-first data product (GTM.AI). WhoLayer identifies website visitors (person-level for US traffic, company-level free) and offers contact data through an API and MCP server, all from one credit wallet, starting with a free plan with 100 credits a month. Pick ZoomInfo if you need depth of enterprise company and contact data.

Checked November 4, 2026. Every ZoomInfo figure links to its source.

## Where ZoomInfo is stronger

An honest list. If one of these is what you need, it may be the better pick.

- Depth of enterprise company and contact data
- Intent topics, ABM display, and retargeting
- Free search and lookup in GTM.AI, plus an open-source CLI
- Conversation intelligence and a broad sales suite

## Where WhoLayer is different

### Built for agents

A data MCP server with 13 tools and a REST API with an OpenAPI spec. Per-key daily caps, a 250-credit default ceiling per call, read-only keys, and idempotent retries keep an agent's spending predictable.

### Contact data with checks

Work and personal emails come with a risk grade, mobiles come with a carrier and line-type check, and you can verify lists of up to 1,000 emails per call.

### Company-level ID is free

Company identification is free and unlimited on every plan. Person-level ID is US-only and charged once per person per month; repeat visits are free.

### One wallet, published per-result prices

Visitor ID, Shopper ID, the Data API, and the MCP server draw from the same credits, and every credit cost is listed on the pricing page. Misses aren't charged.

### Opt-outs honored everywhere

Opted-out and suppressed people are never returned, delivered, or charged. Global Privacy Control signals are honored, and the rules we enforce are published as a machine-readable policy.

### Monthly plans, spend caps

Monthly plans stop at the end of the billing period, and you can set a hard monthly spend cap so overage never surprises you.

### WhoLayer isn't the right fit if

- You need a large global contact database for prospecting by country. WhoLayer's person-level data is US-only.
- You need person-level identification of visitors outside the US. WhoLayer identifies people for US traffic only; elsewhere it's company-level, after consent.
- You want a full ABM advertising suite, an on-site AI chat agent, or a built-in sequencer and dialer. WhoLayer identifies and enriches; it doesn't run ads, chat, or send email for you.

WhoLayer plans
| Plan | Monthly | Credits | Overage |
| --- | --- | --- | --- |
| Free | Free | 100 | None |
| Starter | $49 | 1,000 | $0.060 a credit |
| Growth | $199 | 5,000 | $0.050 a credit |
| Scale | $799 | 20,000 | $0.045 a credit |

Example: identifying 1,000 US people a month uses 1,000 credits. The cheapest fit is Starter at $49 a month. Repeat visits by the same person in a month are free, and company-level ID doesn't use credits.
